Same thing happened to me at the Circle K in Jalan Padma Utara. When they tried it a second time my wife was with me and when I asked her to get the Tourist Police stationed just up the road the note magically changed back to a 100K. After these incidents I made sure that the notes passed over never left my sight or I used 50K notes.
